DRIVE FOR PAPER-MAKING MACHINES.

' To all whom it may concern/.-

Be itknown that I, Gusrav-Knnrnnnnnenn, of Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Drives for Paper-Making Machines, of which the following is a specification.

This invention pertains to mechanism for transmitting the driving motion from the main driving-shaft of a paper-making machine to such machine, and for permitting of the adjustment of the relative speeds of the various parts, as hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a side view of portions of a paper-making machine fitted with my improved drive; Fig. 2, a transverse section of the same near one of the presses, and Fig. 3 a plan of the idlercarrier and its adjusting mechanism.

In the drawings, A represents a portion of the Fourdrinier part of a paper-making ma chine; B, the coucher; O, the first press; D, the second press; E, a portion of the drier part; F, the framing of the machine; G, rollstands, and H rolls, all constructed and arranged as usual.

I represents aline-shaft or main drivingshaft placed parallel to the paper-making machine, near the floor, and as close against the side of the machine-framing as its operation will permit; J, bevel-gears on the parts of the papenmaking machine to which motion is to bevel-pinion shafts at each of said bevel-gears; L, bevelpinions on said shaft and engaging said bevelgears; M, a conical drum on each bevelpinion. shaft; N, conical drums on the lineshaft at positions to correspond with the drums M, and arranged with their tapers oppositely disposed with reference to the taper of the drums furnishing bearing-supports for the line-shaft and for the bevel-pinion shafts; P, frictionidlers arranged to be held in contact with the conical drums and transmit the motion from the drums upon the line-shaft to the drums upon the bevel-pinion shafts; Q, carriers in which the idlers are journaled; R, screws loosely journaled in the floor-stands, across which they pass, and engaging with their threads the carriers; S, a rod reaching from M; 0, floor stands or housings the carrier backward across the machineframe; T, a handle on the rear end of the rod S; U, a nut-holder secured to the rear side of the machine-frame at the end of the rod S; V, a nut upon the threaded part of the rod held in the nut-holder, and collars upon the screws R, engaging one of the floor-stands, to prevent end motion of the screw.

A pair of the conical drums,&c.,is supplied at each portion of the paper-making machine whose relative velocity of motion is to be altered in adjusting the tension of the paper. The lineshaft runs at high velocity,to transmit motion through the drums, idlers, and bevel-gears to the different parts. The relative velocity of the two drums of each pair will be governed by the position of the idler, in an obvious manner, and this position may be adjusted and altered by means of the screw B, which traverses the idler along the face of the drums, whereby the different portions of the paper-making machine may have different speeds of rotation while receiving motion from a single line-shaft, and the speeds of the parts may be adjusted while the machine is at work. The idlers are held into forcible contact with the drums by the strain of the screw-rods S. By turning the handle T in one direction theidler will be brought into forcible contact with the drums, and by turning the handle in the other direction the idler is relieved from its forcible contact, and the upper cone ceases its motion. The device thus serves as a means for stopping and starting the parts of the machine as well as for adjusting the speed.

. The screw R,while it engages theiioorstands, is carried in bearings of such size as not in the least to interfere with the movements of the carrier as the idler is adjusted to or away from the drums.

The rod S is connected to the carrier by a joint-pin, X, as shown, and the nut V is articulated in its holder, as shown, whereby the rod does not in any manner interfere with the traversing motion of the carrier.

The line-shaft may receive its motion from a motor through any suitable means, and tangent-gearing may be substituted for the bevelgearing, if desired. v

I show the bevel'pinion shafts arranged verdrums, and means for adjusting the idlers to and from the drums in starting and stopping of the machine parts, substantially as and for the purpose as set forth. 2. The combination of a longitudinal serie of machineparts to be independently driven, a line-shaft disposed parallel to such series of machine parts, and provided with conical drums, a short shaft disposed parallel to said line-shaft at each of said machine parts, contically over the line shaft; but such arrangement is not at all essential. The bevel-pinion shafts may be disposed as found most convenient as to height and position with reference to the line-shaft, and the bevcl-pinion shafts do not need to be arranged uniformly. I While I entitle my invention as a drive for paper-makin g machines, and While Iillustrate it in connection with paper-making machines, I do not limit my invention to use With paper- E making machines. On the contrary, I conteml plate its application to any longitudinal series l of independently-drixg en machine parts, as i hereinafter distinctly pointed out. I
